Nolan plots the y-intercept of a line at (0, 3) on the y-axis. he uses a slope of 2 to graph another point. he draws a line through the two points. which equation represents nolan’s line?

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-intercept

In this problem we have

Remember that the y-intercept is the value of y when the value of x is equal to zero (point 0,3)

substitute the given values

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
